PHP Script, Quickly Create Facebook Instant Articles With Just A Few Clicks, No HTML Experience Needed. Always have in mind that Facebook created the Instant Articles' platform for the MOBILE USERS, ie. The users of smartphones, tablets, etc.
If that was not true, then Facebook would have NO REASON AT ALL for pushing their money to that Instant Articles' platform, since Facebook users (either those that use the web to browse the Internet or those that use smartphones, etc) can read perfectly what is posted in Facebook, in their timeline, in pages, etc. Hence, since posting articles in your Facebook account IS POSSIBLE without the need of the Instant Articles' platform... then there must be a really good reason why Facebook did invest on that platform.
